CIGAR BUNCHING.

Application led March `29, 1922. Serial No. 547,671.

To all whom t may concern.'

Be it known that I, BERNARD 'LBERMAM a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented a new and useful method and means for lCigar Bunching, of which the following is a specification.

The invention relates to improvements in cigar bunching. The object is to provide improved method and means for delivering accurately measured charges of scrap tobacco from a source of supply, such as a hopper, to the usual bunching aprony of a bunch rolling table.

The specialpurpose of the invention is 'to improve the eiiiciency and accuracy of measuring the charge, and then separating said charge cleanly and effectively, from the mass in the supply hopper from` which the charge is received; so that said charge, accurately measured and cleanly separated, is delivered to the bunching apron, or to the intermediate means for conveying said charge to said apron. This invention includes improved method and means for introducing the scrap to the measuring pocket, and improved means for severing any `portion of tobacco whichmay project from the measuring pocket into the hopper, as the margin, for example the edge 16, of said pocket passes the cooperating margin or edge 28 of the hopper.

This invention comprises improvements in the method and means described in my co-pending application Serial No. 515,446 filed Nov. 16, 1921.

Referring to the drawings, which illustrate merely by way of example suitable means for effecting my invention- Fig. 1 is a plan view of the measuring element.

Fig. 2 is a cross-section on line 2--2 of Fig. 1.

Fig. 3 is a perspective view of the shearing member or knife.

Fig. 4 is a vertical cross-section of said measurin element, a portion of the hopper and associated parts, the measuring element in the receiving position.`

Fig. 5 is a similar view, the measuring element in the discharging position.

Fig. 6 is a similar but more fragmentary section, showing member 7 in an intermedi ate position,

Fig 6* -is 1,a similar fragmentary ,section showing member 7 in a still di'erent position.

Fig. 7 is a view in perspective of, member one wall inclined to the axis of body 7.

This pocket 9 is provided with an adjustable plate or wall 10 operated by the adjusting screw 10 for adjusting the depth of the pocket, all of which is clearly described in a co-pending application, and forms no part of this application; On the side wall kof the pocket 9 which is inclined to the axis,

is provided the cutting member or knife 11, securely fastened to said wall by the screws 12 projectingV through slots 13. These screws 12 are reached, when it is desired to move the same, by means of a screw driver inserted through openings 14, normally closed by the screws or threaded plugs 15.

The knife 11 has a sharp cutting edge 16 on its pocket side, which cutting edge should preferably extendy a very slight distance above or beyond the true periphery of the cylindrical body 7. This knife or cutting member 11 is also provided in its bottom face or edge with two threaded openings 17, for receiving theadjusting screws 18.

The lower part of the hopper 19 is provided at one lower margin with the arc lip 2() for cooperating with the solid circumferential part of member 7. A part kof the opposite lower margin of hopper 19 is cut away, as at 21, thereby providing an opening conforming in width to that of the pocket 9. Beneath the opening 21 in hopper 19 isprovided the member 24 having a reverse curve formation 25 from the opening 21 downwardly to a point on the periphery of cylinder v 7. This member 24 is preferably bolted to the underside of hopper 19. This forms. arecess or pocket 26, corresponding in width to they width of pocket 9, for the purpose hereinafter described. Upon the underside of the member 24 is provided the knife or cutting member 27, having a cutting edge 28 adapted to cooperate with the cutting edge 16 of `knife ,or 'getting member 11, which is member 24 by means of screws 29 in slots 8O'.v

[n operation.

Then the member 7 is in the position shown in Fig. a, pocket 9 is entirely open to the hopper 19 which provides the supply of moisty scrap tobacco. This scrap will naturally fall Vinto the pocket 9 and fill the same. As the tobacco is moist however itsfmovement is somewhatsluggish and not always uniform, so that the charge in pocket 9, while the same remains in the position shown in Fig. 4, may vary in amount and density. This condition however is corrected in the following operation. As the member 7 moves from the position shown in Fig. l to the position shown in Fig. (i, it will be noted that the pocket 9 now registers with a pocket or offset-recess 25 Vevtending downwardly fronithe main part of hopper 19. VThis pocket or recess 26 corresponds in width with the pocket y9 and is provided witha curved and inclined wall 25 facing the pocket 9. Y All of the communicating space of recess 2G and pocket 9 is filled with scrap tobacco in a more or less loose condition. The result of this construction and arrangement is, that as the lpocket 9 moves from position, Fig. 6, to position, Fig. 5, the scrap tobacco in said combined space tends to move with pocket 9, andv the part. in engagement with wall 25 tends to slip along said inclined wall 'toward the pocket. This results in pressing with gradually increasing;pressure, the greater part of the `scrap contained in said recess Q6, into the pocket 9 by the time the knife edge 16 cooperates with the knife. edge '28, and any remnant of scrap Aprojecting,beyond the pocket between said knife edges, as they come together, is sheared oft cleanly, Aso that 'a clean cutuniform charge, of even density throughout its bulk, is brought to or slightly beyond the position shown in Fig. 5.

In moving inthe counterclockwise direc tion slightly past the position shown inFig. 5, the member 7 lcomes to a stop and the charge ofscrap is discharged from pocket 9 into trough 31.

ln the return movement of member 7, in the clockwise direction, it will be notedthat pocket 9 is open to recess 26 andl also to the space outside the hopper, as indicated in Fig. 6a. The movement however of mem-` ber 7,'which is capable of` about sixteen discharge movements per minute, is of lsuf-V ficient speed to prevent any kof the compara tively slow i'novingscrap which passes from recess 26 into pocket 9,' from escaping from pocket 9 before the margin 32 passesknife edge 2S, 'so that-no scrapis discharged from pocket 9 daring said return movement of member 7, On the other hand said move A reaches the position, Fig. l, the pocket is well `filled with scrap in comparatively loose formation. In a copending aopplica tion l have shown means, operating in the hopper just over the pocket, for cooperating in Athe filling and packing action; but the filial filling and packing action is secured by the recess 26 and the wall formation 25, above described.

The shear/ing ope/ration.

In view of the fact that the scrap tobacco is quite moist, the particles of tobacco leaf are very soft, and 'the tendency is, where a margin of the pocket engages a margin of the hopper, to crush the particles of tobacco projecting between said enacting margins. This is liable to result in undesirable conditions, such as mashing the soft tobacco and thereby causing a clogging in the vicinity of said coacting margins. have found it most important therefore to provide means for securing a clean shearing action between said coacting margins so that any particles projecting between said margins, as the same come together and pass each other, shall be cleanly sheared olf and not crushed so as to clog and jam the machine. ln order to secure this result it .necessary Athat the coacting knife edges besides operating the one at an angle with the other, be sharp and perfectly adjusted, solthat/their coaction shall be a truc shearing one. For this purpose l provide means for adjusting the knife l1 in the pocket i). This comprises the set-screws 1S, threaded into Vthe lower edge of knife member l1. The slots 13, through which the screws l2 project, providek a considerable leeway for vsuch adjustment, andalso permit regrinding the knife edge from time to time as required. This is obviously a distinct advantage over devices of this type, where the knife used is not adjustable, since a Vsingle nieking or damaging of the knife edge 16 will render the whole knife useless. W'ith the combined 11 and knife 2T, it is now possible to secure and .maintain a perfect shearing eoaction between the two, equa-l to the action of a pair of well made shears.
